Plenum to runner Hi-flow gaskets
Where does one find the plenum to runner gaskets. I have the Edelbrock 3865 large runner. All the gasket kits come only with the runner to base gasket. Who does that? Stupidest thing I've ever seen. $70 for half the gaskets .Ridiculous. Anyway can the stock one be cut out enough?

Stock ones work fine, the runner ports are not bigger than the stock gasket bores. I just installed a set on mine.
